I can not find a replacement because there are no numbers to cross reference and a new one from Sonex is $500. I think the material would be less than $100 and it would be a good learning experience! Thanks again, Tom ________________________________ Message 2 _____________________________________ Time: 04:14:19 PM PST US From: "Robert L.

Have you un-wound the existing wire, measured its length and put a caliper or micrometer on its diameter? I have access to several aircraft motor wind shops that will have class-h insulation magnet wire suited to your task.

Nuckolls, III" Subject: Re: AeroElectric-List: Stator By the way, how much load is on this alternator in flight? What kind of rectifier/regulator do you run? There are two techniques for voltage regulation on PM alternators . . . the legacy, easy to do, shunt regulator that essentially has the alternator running full load all the time. Then there's the more modern series regulators that load the alternator only to meet system requirements. This winding may have failed because of a shunt regulator . . . I can help you make sure that your newly rewound alternator is not unnecessarily taxed.

When I replaced mine due to a pinched wire the whole kit was $140 minus the regulator.

How about posting a pic with accurate measurements? Here's the 1st site I found with a google search for 'motorcycle alternator stator': http://www.jpcycles.com/motorcycle-stators It shows pics of dozens of models; you should be able to narrow down the choices a lot just by appearance, and then counting generating coils & trigger coils (likely one or at most two trigger coils; should be obviously different). You can also try googling 'outboard motor alternator stator'. Or better yet, have you asked on lists that are frequented by users of aerovee engines? Odds are good that *somebody* has already found an aftermarket solution.
